Brilliant

truly great work!... not a failure at all.. its a start

If you're using a phone, buy a cheap gimbal. That will improve on the steadyness. However if you really want to zoom and focus you need a decent camera something with an actuall lense.. You can also see the light is very bad. I hope you plan to bring out new video's about sat/mil reception. I was enjoying those. :-)

boring? i dont think anyone thinks that

what did you reduce the sampling rate to?

Sounds like an speed up morse code with eerie ambiance

Very Informative. Thanks!

Spotting with SDR would be interesting... And I'm asking myself.. does the grass mower have any SDR signal? So it is traceable for the tower?

For Those Who Don't know : In 1977, An Ohio Astronaut Were Looking In The Stars On The Sagittarius Continuation, But Suddenly He Heard An Sound Through The Radio Controls, Signaling to a Group Of Stars That Lasted A min And 12 Seconds, This is Called Wow! Signal, Scientists Or Astronauts Don't Know After 48 Years, Maybe We Know It Someday

I lived in a city with a military air base for a while, and it never occurred to me that I could just... go there and watch... :D (Though it was not in my home country, so I guess I would have _really_ hard time explaining I'm not a spy if they came and asked.. :)) )

Spotting is addictive. Thanks for sharing.

What is needed to get ANY data from Juno? What would be the minimum diameter of antenna and other equipment and any rational for them? I am thinking any radio signal from Jupiter is impossible to get, because Jupiter is such a radio noisy planet. Am I about right? But I want to prove me wrong, so could you provide minimum specs to get the data from Juno or other planetary probes, and any calculation that can justify it? Are those equipment within reach for say, $10,000 budget?

Can you get any signal from Hubble telescope of James Webb telescope? What I am curious is, HST, the orbital period is like 90 minutes. For the earth bound telescopes, we have about 12 hour night sky. For HST, it's only 45 minutes and the sky is moving a lot faster for it. So what is the advantage of having the telescope in LEO? Anyhow, can you get the signal from HST or JWT please? If you can download any data from them, that will be even more great.

TY .. very informative

Your calculator doesn't work, it doesn't do anything at all.

Do you have the stl for the LNB mount? You can see the grey one @3:38 I tried finding on your thingiverse but didnt see it

This is great, and the antenna calculator is really nice! Thank you so much! I just don't understand how does this relate to the dish. I know how to make a helical antenna, but where do I place it in the dish, how do I calculate the position, number of turns in the antenna, etc. given a dish I have.

At what frequency do those walkie-talkies that are heard via satellite broadcast?

8:52 Did you just call me nobody? 🧐😂Good idea though, there seems to be little to no "entry level" information and particularly nothing useful on YT. I'll put it on my list. 12:24 The Diameter of a Dielectric Resonator is roughly the speed of light divided by [the desired frequency times the square root of the relative permittivity of the material used]. The material is usually some barium and titanium oxide. At the resonance frequency, the electric field moves in circles inside the resonator, like being stuck in a roundabout. This is called the TE01δ (say: TE 01 delta) mode. The little striplines next to it are used to couple some of the oscillator's signal into the "roundabout" and the other stripline is used to couple some of the signal in the roundabout back into the amplifier, thus closing the loop (and fullfilling the Barkhausen stability criterion). The dielectric resonator is usually positioned 1/4th of a wavelength away from the end of a microstripline as the E-field has a maximum peak there. If you see one microstripline being longer than the other, one is simply 1/2 wavelength (or multiples of 1/2) longer than 1/4th wavelength. Which changes nothing from an impedance and field strength standpoint, but reduces direct coupling from one microstrip into the other. This roundabout effekt of the TE01δ mode only works at the correct resonance frequency. The reason why they can be tuned with metallic objects, such as screw, is, because there also is a magnetic field influencing the flow of traffic in the roundabout. Changing the permeability by disturbing the H-field will shift the resonance frequency.

16:55 casually flexes a 2.5m dish holy crap

Remember there are collaborating receiving stations all across the globe. and the signal can be received anywhere within the footprint.

Hello Friend. Thank you, you helped me a lot. Ukraine will be free. Putin is a bastard.

why is wow signal overly quite scary

That list of satellites, where is the source of it ?

Hola amigo, gracias por el video, me sirvió mucho. Quiero saber como debo configurar el SdrSharp. gracias 73 LU9ERV

👍

👍

Your channel is super underrated.

IMHO you should point the C LNB as same as that helix antenna direction, facing the offset focus of dish.

Theoretically, how far your signal can travel to? Alpha Centauri? Zeta Reticuli? Sirius? The other end of the Milky Way? What’s the equation and numbers to use for that?

Thank you, this was a very informative and interesting video

Hi Derek, thanks for all the super interesting videos, you have inspired me to start experimenting with satellite reception, it would be interesting if you could do a series on some of the different satellites that have interesting downlinks available to receive, what they transmit and how to receive them, maybe starting with geostationary satellites

50dB is pretty high gain.

Do you think that the WiFi grid antenna can access GOES Sat from London UK?

can you get like military intel typehigh quality zoomed in images?

Thank You for all your great videos and knowledge , more videos please…Great English… My experiences range from : NOAA APT , HRIT , GVAR and now GOES GRB. Best wishes from Colorado , USA..

I can't understand how GPS sats appeared on 2,2GHz.

One of the most 'effective' tutorials I've seen on YT. Straight to the point, no lengthy bla bla and heaps of information. Info is the right mix between practical en theoretical info. Really well done.

Can a normal TV antenna work fine?

I'm sure you're from sk/cz xdd

nice, russia comes to the rescue, when all lrpt seems lost.

Are you ucrainian n-zi?

8:03 Love you do it yourselfing 🙂

34:32 rat race coupler used as balun.

I had to take apart some 5G prototype hardware (LTE picocell) for a job back around 2010, and it had anti-tamper features: A battery-backed up RAM with the encryption keys and subscriber information, and a thin wire, embedded into both halves of the plastic case, connected the two. It was like a spider's web. I was warned of this situation so was able to find and bypass wire before opening. :D

I would guess that the SOIC-8 packge next to the PA is just a run-of-the-mill P-FET that switches the power to the PA. Pins 1-3 and 4-8 are shorted together, and hat big heap of caps right next to it also points in that direction.
